Spin Engineering of Dual‐Atom Site Catalysts for Efficient Electrochemical Energy Conversion
Advanced Materials, EarlyView.This review highlights recent progress in spin engineering of dual‐atom site catalysts (DASCs), emphasizing how spin‐related properties enhance electrocatalytic activity, selectivity, and stability. It summarizes cutting‐edge developments in dual‐atom catalysis, discusses the underlying spin‐catalysis mechanisms and structure–performance relationships,

Advanced Materials, EarlyView.Observation and detection of neurotransmitter dynamics in aqueous system has been hurdle for analytical fields due to its weak and reversible nature. A terahertz‐nanodisc metasurface which implements comprehensive detection over conformational change and selective sensing is introduced. Utilizing the THz regime photonics and biomimetic environment with

In psychiatrically healthy individuals, overweight women but not men have lower tryptophan levels
Pteridines, 2015 Gender differences in tryptophan (TRP) breakdown in obese individuals have been previously reported. This could be both contributory to, as well as a consequence of, gender differences in mood changes among obese people.

Advanced Materials Interfaces, EarlyView.This study presents a platform for simultaneous monitoring and electrical control of cellular responses at the cell–electrode interface. The platform delivers tunable yet uniform electrical cues to cells, revealing that optimal electrical stimulation (ES) conditions vary across cell types.

HeliyonBackground: Tryptophan is an essential amino acid with anti-inflammatory and immunomodulatory effects. However, the absorption of amino acids including tryptophan is relatively slower than the absorption of dipeptides. Therefore, we have two aims in this

Phenotypic recurrent selection to improve protein quality in non-opaque maize populations
Scientia Agricola, 2002 Maize (Zea mays L.) protein is considered to be of low quality due to low levels of the essential lysine and tryptophan amino acids. An alternative to solve this problem is to use the opaque-2 gene, which improves the level of these amino acids, but has ...

Folate, neopterin and kynurenine pathway in patients with statin therapy
Pteridines, 2016 Statins, widely used antihyperlipidemic drugs, also have immunomodulatory properties independent from their lipid lowering effect. Even with slight modulations in the immune system, pteridine levels can display changes.

Advanced Synthesis &Catalysis, EarlyView.The halide motif is ubiquitous in organic synthesis, facilitating fine‐tuning of molecular properties and functionalization using substitution and cross‐coupling reactions. Combination of different flavin‐dependent tryptophan halogenases enables the installation of novel halogenation patterns on l‐tryptophan, which can be orthogonally addressed in ...
